"I just purchased this set today from a local walmart and as soon as I returned home I opened it. No more than 10 seconds after opening the smaller plastic bag with the heads and other assorted pieces did I notice something was off. The head for the Black Widow minifigure was substatuted with a male minifigure head with a gaping, laughing mouth. I just found it quite comical that all the possible heads, it was one that was just laughing in my face. Other than this, the set was well worth what it was being sold for ($12 and some change). Has decent playability and comes with pretty cool minifigure ( most likely)."
